I know this question has been asked before am I have tried most of the solutions and still having issues. So, I am on Mac OS Monterey (12.6.1). Installed Python 3.7.12 (using pyenv). Using Poetry for dependency management. I did the below steps after activating & deactivating the virtual environment using poetry (source $(poetry env info --path)/bin/activate)

1. Removed existing pycurl using brew
2. Installed openssl (brew install openssl)
3. Verified ssl installation directory

  brew --prefix openssl
  /opt/homebrew/opt/openssl@3

  $ ls -la /usr/local/opt/openssl@3
  lrwxr-xr-x  1 xxxxxx  admin  25 14 Dec 22:57 /opt/homebrew/opt/openssl@3 -> ../Cellar/openssl@3/3.0.7

4. Install PyCurl specifying inline the above openssl install directories like this

  PYCURL_SSL_LIBRARY=openssl LDFLAGS="-L/opt/homebrew/opt/openssl@3/lib" CPPFLAGS="-I/opt/homebrew/opt/openssl@3/include" pip install --no-cache-dir pycurl

PyCurl installs without any problem but when I try to import pyCurl I get the following error message.

Python 3.7.12 (default, Dec 14 2022, 22:00:27)
[Clang 14.0.0 (clang-1400.0.29.202)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import pycurl
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: pycurl: libcurl link-time version (7.79.1) is older than compile-time version (7.86.0)
>>> quit()

PS:

1. poetry env info --path does return the correct poetry virtual env path.

2. I tried switching my Python version to 3.8.X and 3.9.X and still having the same issue.

3. I also updated my curl version to 7.86 using brew and doing a brew --version does conform the same.

$ curl --version                                                                                                                                                                                     ✔  at 11:13:19 pm  ▓▒░

What am I missing from the above steps? Thank you in advance for your time... :)

After a lot of trial and errors I managed to find a way around this. The easiest way for me was to download curl and manually set the path for PyCurl compilation. Following were the steps I did to resolve my issue

$> pip uninstall pycurl
$> brew uninstall curl

# Install openssl to compile pycurl
$> brew install openssl@3

# If you already have openssl@3 installed run the following
# command and note the path of LDFLAGS an CPPFLAGS
$> brew info openssl@3

# Downloading latest version of Pycurl
# I downloaded curl to my HOME path
$> wget https://curl.haxx.se/download/curl-7.86.0.tar.bz2

# Unzip 
$> tar -xf curl-7.86.0.tar.bz2

#Add the following to .zshrc
export PATH="$(HOME)/curl-7.86.0/bin:$PATH"
export LDFLAGS="-L$HOME/curl-7.86.0/lib -L/opt/homebrew/opt/openssl@3/lib"
export CPPFLAGS="-I$HOME/curl-7.86.0/include -I/opt/homebrew/opt/openssl@3/include"

# Install PyCurl
$> pip install --no-cache-dir --compile --install-option="--with-openssl" pycurl

#Checking if the installation went right
$> python -c "import pycurl"

Since I was using Poetry the above steps did not add PyCurl to my virtual env. I went into my project, activated my virtual env (source $(poetry env info --path)/bin/activate) and then ran pip install --no-cache-dir --compile --install-option="--with-openssl" pycurl

Hope this helps !!!.
